description The present invention relates to a polishing apparatus having a surface-property measuring device for measuring surface properties of a polishing pad which is used to polish a substrate, such as semiconductor wafer, and a polishing system including such a polishing apparatus. The polishing apparatus includes a surface-property measuring device (30) for measuring surface properties of a polishing pad (2), a support arm (50) for supporting the surface-property measuring device (30), and a moving unit (53) coupled to the support arm (50) and configured to move the surface-property measuring device (30) from a retreat position to a measure position.
